Subject: Lockup in barely-patched 3.7.5, maybe wifi/ath9k or i2c related
Date: Tue, 29 Jan 2013 18:18:27 -0800 [thread overview]
Message-ID: <510882F3.4080000@candelatech.com> (raw)
I've been seeing strange lockups since 3.7.4. Not so easily reproducible
most of the time. Previous lockups looked to be rcu/rtnl based, but the one
below has a bunch of i2c stuff in it.
Patches applied are a few wifi patches from upstream and one hack to make
ath9k able to over-ride the eeprom regdomain.
I *think* the decodes are proper, I had to switch back to this patch
set and re-compile....
